The trachea intubation is an important rescue technique commonly used in emergency treatment work, is one of the most widely applied, most effective and most rapid means in respiratory tract management, is the basic skill which must be mastered by medical staff, and plays a vital role in rescuing the life of a patient and reducing the fatality rate.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: a method for using a disposable endoscope is provided, which comprises a visual tube core, a wireless transmission handle and an endotracheal tube, and comprises the following steps:
the method comprises the following steps: detecting and confirming that the equipment is normal;
step two: properly shaping the front end of the tube core of the endoscope;
step three: placing an endoscope tube core into the tracheal tube;
step four: before intubation, the oral secretion of the patient is sucked clean;
step five: searching for an epiglottis;
step six: bypassing the epiglottis;
step seven: and (5) placing a pipe.
The first step of detecting the equipment comprises the steps of firstly checking whether the aseptic package of the endoscope tube core is intact, then slightly pulling a cable ring, connecting the endoscope tube core with a handle, turning on a handle switch and confirming that a lens lamp is on; and opening the display screen to confirm that the signal connection between the display screen and the handle is smooth and the image is normal.
The endoscope tube core placing process in the second step is that the endoscope tube core is straightened, proper lubricant is coated on the shaping position, and then the endoscope tube core is placed into the tracheal catheter along the righting direction in the position confirmation direction, wherein the endoscope lens is positioned within 0.5-3cm of the inclined plane of the tracheal catheter; the tracheal catheter is fixed by a fixer.
The endoscope lens is positioned within 0.5cm of the inclined plane of the tracheal catheter; the lubricant is one of paraffin, lidocaine gel or lidocaine spray.
The endoscope tube core needs to be plasticized before use, and the plastic position determining method comprises the following steps: the first method is that the head is tilted backwards, and the distance between the chin angle of the mandible and the hyoid bone is measured; second, the pillow is removed and the patient lies down, and the distance from the incisor to the thyroid cartilage is measured; taking the middle points of two marked lines at the front end of the air bag as fixed points; the upper part of the endoscope tube is aligned.
The direction mode of the lens is adjusted in the process of intubation; the lens looks to the left: holding the tube core by fingers to rotate left; the lens looks to the right: holding the tube core by fingers and turning right; the lens looks up: the tube core leans backwards; a tube core is upwards: the tube core is lifted upwards; the lens looks down: the tube core inclines forwards; the tube core is downward: the die is pressed down.
The fifth step is to search for the epiglottis; the method comprises the following steps: the mandible lifting method with one hand; the second method comprises the following steps: single-hand pushing backward; the third method comprises the following steps: a assistant holds the lower jaw with both hands; the middle part of the tube core is held by the right hand; entering into oral cavity through the middle of tongue, and the tube core is not too deep and can be 8-10 cm; searching the uvula on the screen; the tube core should be tightly adhered to the surface of the tongue and inserted downwards along the curve of the oropharynx along the middle of the tongue; when the scope body and the patient form an angle of 45-50 degrees, the epiglottis can be seen.
The method for bypassing the epiglottis comprises the following steps; the method I comprises the following steps of: the tube core inclines forwards, so that the lens winds under the epiglottis (the epiglottis disappears from the screen in the video), the tube core slightly presses downwards by 0.5CM, the tube core moves forwards, the tube core lifts upwards and tilts backwards, and the glottis is visible at the moment; the second method comprises the following steps of left and right winding: when the epiglottis and the posterior pharyngeal wall are tightly attached, the epiglottis cannot be bypassed from the front, the tube body can also be rotated 70-80 degrees leftwards (rightwards), then the tube body is slightly pressed downwards to recover the middle position of the tube body, the tracheal catheter is felt to slide to the back below the epiglottis, and the glottis is searched while the glottis is tilted backwards.
The method for placing the tube comprises the steps that a tracheal ring is seen when the front end of a tube core passes through a glottis at an angle of about 110 degrees; (at the moment, the endoscope can not enter too deep to avoid damaging the front wall of the trachea) the tube core is inclined forward, the left hand pushes the catheter downwards to a proper position, and the right hand withdraws from the endoscope; when withdrawing the tube, the tube core is pulled out towards the foot of the patient; when the molding position passes through the tracheal catheter joint, the endoscope core can be straightened and then withdrawn.
The invention has the beneficial effects that:
1. the tube core type products can be seen, and the whole intubation process is visible, has no blind area and is not damaged. The occupied space in the oral cavity is small, and the oral cavity is suitable for patients with small mouth opening degree, small mandible, megalingualis and other oral cavity abnormal structures who are disliked greatly.
No laryngoscope is needed for assistance, the teeth of the patient are slightly damaged, the stress response is light, and the influence of the hemodynamics is small.
2. The tube core can be shaped arbitrarily and is suitable for patients with high glottis and limited head and neck movement.

Detailed Description
The invention is further described with reference to the following figures and detailed description.
1. Confirming device is normal
Checking whether the aseptic package of the endoscope core is intact.
And secondly, lightly pulling the cable ring, connecting the endoscope tube core with the handle, turning on a handle switch and confirming that the endoscope lamp is on.
And thirdly, opening the display screen to confirm that the display screen is smoothly connected with the handle signal and the image is normal.
2. The core of the endoscope tube is arranged in the tracheal catheter by 0.5cm
Straightening the core of the endoscope, and coating proper lubricant on the shaping position
Note: paraffin, lidocaine gel and lidocaine spray can be adopted, and the reinforced tracheal catheter can be not lubricated.
And secondly, confirming that the lens is placed into the tracheal catheter along the right direction (the position of the blue line is the right direction).
Note: when the medical field is used, the operation fails because the direction of the lens is the reverse direction.
And the lens of the endoscope is positioned within the inclined plane of the tracheal catheter by about 0.5 cm.
Note: because different manufacturers have different types of tracheal catheters, 0.5cm is not the only standard, and the optimal position is that the side of the tracheal catheter can be seen on the screen, but the image watching effect cannot be influenced.
Reason for receding to 0.5cm of tube:
the optimal visual distance of the camera is 0.5-3cm, if an air outlet conduit of an endoscope tube is detected, the endoscope tube is very easy to stick to the wall of a throat after entering, at the moment, a red lens on the lens is indistinguishable, a mirror is retracted into the conduit, so that the lens has a depth of field, and an image is very clear.
And II, if the tube core of the endoscope extends out of the tracheal catheter, the lens is directly polluted by secretions to influence the image effect, and at the moment, the mirror is retreated, so that if a small amount of secretions are encountered, the mirror can be directly hung on the edge of the tracheal catheter, and the image effect cannot be influenced.
III and in the case of intubation, the metal substance is unable to exit the endotracheal tube to avoid damage to the patient's airway.
Fourthly, fixing the tracheal catheter by a fixer
3. Properly shaping the front end of the tube core of the endoscope
Shaping positions:
the method comprises the following steps: head bending backward, distance between chin angle and hyoid bone
The second method comprises the following steps: the distance from the incisor to the thyroid cartilage when the patient is rested
The third method comprises the following steps: the middle points of two marked lines at the front end of the air bag are used as fixed points
The common patient is shaped 7-8cm in front of the tube core at an angle of 70-80 °
The difficult air passage is shaped 4-5cm in front of the tube core, and the angle is adjusted to about 90 °
② to keep the upper part of the endoscope tube in a straight line as much as possible
4. Before the intubation is recommended, the oral secretion of the patient is sucked clean.
5. How to adjust the direction of the lens during intubation:
the lens looks to the left: the tube core is held by fingers to turn left.
The lens looks to the right: the tube core is held by fingers and turned to the right.
The lens looks up: the tube core leans back.
The lens looks down: the tube core inclines forwards.
A tube core is upwards: the die is lifted upward.
The tube core is downward: the die is pressed down.
6. Operation-finding epiglottis (as shown in figures 3, 4, 5)
The first method comprises the following steps: one-hand mandibular lifting method
Note: if we directly put a mirror, the visual field in front of the lens is very small, and often see a piece of red through, the doctor can feel lost and does not know where the mirror is. At this time, a cavity needs to be made, namely, the space below the tongue root is required to be provided, but the space below the tongue root cannot be picked up by the tube core, so that the shaping angle of the front end of the tube core is easily changed, and therefore, the tongue of the patient needs to be blocked by hands and the lower jaw of the patient needs to be lifted. Thus, the space of the oropharynx part can be enlarged, and the catheter can be conveniently placed in.
Note: the motion of controlling the tongue body and slightly lifting the lower jaw is carried out throughout the operation of the user, because: 1. the space of the oropharyngeal cavity is enlarged, and the possibility that the tracheal catheter is blocked near the glottis can be effectively reduced, so that the damage to the laryngeal part of the pharynx is reduced. 2. When a patient with a small amount of secretion meets, the accumulated secretion can be dispersed 3, and when the patient with a larger epiglottis meets, the epiglottis can be lifted by lifting the tongue root.
Note: some doctors intervene to directly touch the mouth of a patient with their hands, and may also use a laryngoscope to hold the tongue, ask an assistant to help hold up the patient's mandible, or use the oropharyngeal airway to block the tongue. Thus, the purpose of opening the space under the tongue root of the patient can be achieved.
The second method comprises the following steps: one-hand pushing head backward bending method. Not suitable for patients with limited neck movement.
The third method comprises the following steps: the assistant holds the mandible with two hands, and the clinical feedback of the method can ensure that the oropharynx space is more fully opened.
Holding the middle part of the tube core by the right hand. The tongue is inserted into oral cavity through the middle of tongue, and the tube core is not too deep, 8-10 cm. The uvula is now looked for on the screen.
Note: the middle part of the tube core is held by the hand for convenient operation, the little finger is close to 12cm, the distance from the incisor to the glottis is 12cm, and when the little finger touches the mouth side of a patient, the mirror entering depth is judged to be in the glottis hole.
Note: the tube is not too fast and too deep, 8-10cm is enough, and the uvula is seen when the tube core angle is about 15-20 degrees.
Note: there are three ways of entry:
the approach from the middle of the mouth is from the middle of the mouth.
Right side molar approach: when the thorax of the patient is higher or the mouth opening degree is smaller, the patient can enter from the right molar to horizontally rotate and find the uvula.
Esophageal withdrawal method: the tube core is firstly put into the esophagus and then is tilted backwards while retreating, and the glottis is found.
The tube core is tightly adhered to the surface of the tongue and is inserted downwards along the curve of the oropharynx along the middle of the tongue.
Note: in clinic, the doctor will not find the epiglottis because the mirror is not close to the tongue surface, the doctor usually moves the mirror down along the hard jaw, what he can see is in front of the lens, and most likely the epiglottis is just above the lens, but we cannot see from the screen. Therefore, the tongue surface is required to be tightly attached to the tongue surface during operation.
Fourthly, when the scope body and the patient form an angle of 45 to 50 degrees, the epiglottis can be seen
7. Bypassing the epiglottis (as shown in figure 6)
The method comprises the following steps: up and down winding
Oblique core, making the lens wind under the epiglottis (the epiglottis disappears from the screen in the video)
② the tube core is slightly pressed down by 0.5CM and moved forward
Note: when a doctor operates, the doctor can almost see the epiglottis, namely the doctor can not put the mirror below the epiglottis, especially for patients with larger epiglottis, and the doctor often directly pushes the mirror to the position of the epiglottis valley. When the problem is met, the mirror and the epiglottis are kept at a certain distance, the mirror body is inclined forwards, and the hand has a downward force, so that the front end of the mirror easily falls below the epiglottis.
Note: patients with particularly large epiglottis may also have the tubular core slid from the side of the epiglottis to below the epiglottis.
Note: when a patient with a large epiglottis encounters and the mirror cannot cross the epiglottis, the mirror can enter the esophagus and then look for the glottis while moving back and facing backwards.
Thirdly, the tube core is lifted upwards and backwards, and the glottis is visible at the moment.
Note: the esophagus is below and the trachea above, and if the mirror passes through the epiglottis, it will go further downwards and directly into the esophagus. Therefore, when the mirror is placed under the epiglottis, the user can slightly lift the mirror body by hand to make the front end of the mirror attached under the epiglottis, and at the same time, when the mirror is tilted backwards, the glottis can be seen at an angle of about 90 degrees.
Note: when the angle is adjusted, the catheter must be pinched forcefully to drive the mirror body to rotate together, and particularly when the reinforcing tube is used, the catheter is prevented from rotating, but the angle of the mirror is not changed.
The second method comprises the following steps: left and right winding
When the epiglottis and the posterior pharyngeal wall are tightly attached, the epiglottis cannot be bypassed from the front, the tube body can also be rotated 70-80 degrees leftwards (rightwards), then the tube body is slightly pressed downwards to recover the middle position of the tube body, the tracheal catheter is felt to slide to the back below the epiglottis, and then the glottis is searched while the glottis is looked for when the trachea catheter is tilted backwards.
8. Pipe placing device
The tracheal ring is seen with the anterior end of the tube core through the glottis at approximately a 110 ° angle. (at this time, the endoscope cannot enter too deeply to avoid damaging the front wall of the trachea) the tube core is inclined forward, the left hand pushes the catheter downwards to a proper position, and the right hand withdraws from the endoscope.
Secondly, when withdrawing the tube, the tube core is pulled out towards the feet of the patient. When the molding position passes through the tracheal catheter joint, the endoscope core can be straightened and then withdrawn.
Note: the tube core is already shaped like an L, and when the tube core is withdrawn, if the tube core is pulled upwards, the tube can be easily taken out. We should withdraw the wick towards the patient's toe.
Note: A. when we get lost in the mouth, we go backwards first and then forward when finding the anatomical landmarks.
Each device has a learning period, and the accumulation of more than ten cases is needed, so that the device is recommended to be operated on simple patients, and after the device is used skillfully, the device can help people to solve the problem when people encounter difficult airways.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent modifications made by the present invention and the contents of the drawings or directly or indirectly applied to the related technical fields are included in the scope of the present invention.

7. The method of using a disposable endoscope according to claim 1, characterized by that, the method of finding epiglottis in the fifth step is; the method comprises the following steps: the mandible lifting method with one hand; the second method comprises the following steps: single-hand pushing backward; the third method comprises the following steps: a assistant holds the lower jaw with both hands; the middle part of the tube core is held by the right hand; entering into oral cavity through the middle of tongue, and the tube core is not too deep and can be 8-10 cm; searching the uvula on the screen; the tube core should be tightly adhered to the surface of the tongue and inserted downwards along the curve of the oropharynx along the middle of the tongue; when the scope body and the patient form an angle of 45-50 degrees, the epiglottis can be seen.
8. The method of use of a disposable endoscope according to claim 1, characterized in that said method of bypassing the epiglottis is; the method I comprises the following steps of: the tube core inclines forwards, so that the lens winds under the epiglottis (the epiglottis disappears from the screen in the video), the tube core slightly presses downwards by 0.5CM, the tube core moves forwards, the tube core lifts upwards and tilts backwards, and the glottis is visible at the moment; the second method comprises the following steps of left and right winding: when the epiglottis and the posterior pharyngeal wall are tightly attached, the epiglottis cannot be bypassed from the front, the tube body can also be rotated 70-80 degrees leftwards (rightwards), then the tube body is slightly pressed downwards to recover the middle position of the tube body, the tracheal catheter is felt to slide to the back below the epiglottis, and the glottis is searched while the glottis is tilted backwards.
